The latest in surface blasting equipment would be Graco’s Vapour Blasting Machine EcoQuip 2 EQp, EcoQuip 2 EQm & EcoQuip 2 EQs the newest technology in vapour abrasive blasting. This machine precisely injects moist abrasive into the blast stream, which can suppress dust levels up to 92%. This is not to be confused with slurry blasting, which is blasting with slurry of air, water and abrasives that ends up wasting too much water and abrasive and creating a significant pool of contaminated water that is difficult to contain and dispose of.
